Now you can eat all kinds of fresh, off-season vegetables in winter. Most of the vegetables in winter are grown in greenhouses, and there is a particularly important condition for greenhouse cultivation, which is supplementing light. Supplementary light is of great significance to the growth of plants, so LED grow lights are needed to meet this condition.
Vegetable greenhouse solution
1) The reasonable light supplement of LED grow lights is one of the important reasons that affect the harvest of vegetables in greenhouses. Vegetables will photosynthesize under the irradiation of LED grow lights, so that the light compensation point of plants can reach and exceed, combined with the moisture, temperature and humidity in the greenhouse Wait for the plants to grow better.
2) Choose plant varieties for planting according to market demand. Choosing the right plant varieties is the first step to open the market. Reasonable use of different types of LED grow lights to fill light, and good time to market is an important part of occupying the market.
3) One more thing to pay special attention to is the air circulation problem in the shed. If the temperature in the shed is too high, it will cause the loss of vegetable water and affect the growth of plants; when using LED grow lights, don’t worry about this problem. The heat is small and will not cause such problems.

1. Install evenly distributed
Measure the floor area. Multiply the length by the width to get the square meters of the planting area. You can make the right choice based on how much power to provide per square meter, that is, how many LED grow lights are installed per square meter. In this way, each lamp can be evenly distributed, so that the outer edge will receive strong light, so that the light will be more uniform, and the growth of plants will be more effective.
2. Illumination distance
The lighting distance of LED grow lights is very important. You should adjust the points for different plants at different stages, and you must also unify the distance to make the light even more uniform. If the distance is not well controlled, it may harm the growth of plants. The general recommendation is that the germination stage distance: 60 cm, the seedling stage distance: 75 cm, the growth stage distance: 45 cm, and the flowering stage distance: 30 cm.
3. Lighting time
The lighting time of LED grow lights is mainly determined according to plants, which are divided into two types, positive plants and negative plants. Positive plants are more light-loving, and the lighting time can be longer when supplementing the light, usually 18/6 (on/off) or 20/4 (on/off). For negative plants, the lighting time is normal, usually 12/12 (on/off).
4. Dimming level
The dimming of LED grow lights can make plants grow better at each stage, the general germination rate: 30%; seedlings: 50%-75%; growth: 75%-100%; flowering: 100%. Give plants the best growth status.
5. Humidity, temperature
Photosynthesis and transpiration rate are directly affected by temperature, humidity and airflow. Find the best temperature and humidity for your plants between 75*-85*F and 50%-70% humidity, and have sufficient airflow to replenish carbon dioxide.

High light efficiency and energy saving
The electro-optical conversion efficiency of LED grow lamps is more than 20 times that of incandescent lamps, 3 times that of fluorescent lamps, and nearly 2 times that of high-pressure sodium lamps. The application of LED grow lights can greatly reduce power consumption, thereby achieving energy saving.
Spectrum customization
LED grow lights can cover dozens of monochromatic lights with wavelengths. And can realize monochromatic light composite spectrum or full-spectrum white light through monochromatic light excitation phosphor powder, and realize the spectrum customization of different plants.
Adjustable spectrum
The LED grow lights with different light colors can be controlled separately to achieve the function of adjustable spectrum. At present, the adjustable spectrum plant lights on the market are mainly used for scientific research, and the plant lights with adjustable light intensity have been widely used in production.
Less fever
It can touch plants at close range without causing problems such as plant leaves and operators burning. Thanks to the low heat generated by LED grow lights.
long life
The theoretical life of LED grow lights is as high as more than 100,000 hours. Subtracting the influence of various factors, the lifespan of the LED grow light can be left with 50,000 hours. Compared with traditional plant lights, the light decay of LED grow lights after 36,000 hours of operation is still less than 10%. The fluorescent lamp usually has a light decay as high as 30% after 10,000 to 15,000 hours of operation.
Safer and more environmentally friendly
Compared with other traditional plant lights, LED grow lights have no mercury or other polluting elements, and are more energy-saving in terms of power saving. The power supply adopts waterproof male and female plug connections, and has the advantages of IP65 waterproof rating.
These make LED grow lights more popular in the market and are deeply loved by vegetable growers in greenhouses. The development trend of LED grow lights will get better and better in the future.
